EURO IV 4DL1-21E4

The 4DL1-21E4 features a reliable four-cylinder in-line configuration with direct injection technology that gets the most from every drop of fuel whilst maintaining strong performance. The engine uses a 110×135mm bore and stroke setup, creating the right balance between power output and long-term durability.

Turbocharging with intercooling ensures consistent power delivery across varying operating conditions, whilst the common rail fuel injection system provides precise fuel metering for enhanced combustion efficiency. Each cylinder features four valves for optimal airflow management, contributing to the engine’s excellent breathing characteristics.

Performance Specifications

With a displacement of 5.13 litres, the 4DL1-21E4 generates 157kW at 2300rpm, positioning it as a reliable workhorse for medium to heavy-duty commercial applications. The engine’s maximum torque of 780Nm is available across a broad speed range of 1300-1700rpm, ensuring excellent driveability and operational flexibility.

The engine maintains fuel consumption rates of just 196g/kW·h, demonstrating its commitment to operational economy. This efficiency, combined with the robust construction, makes it an ideal choice for fleet operators seeking to minimise running costs without compromising on performance.

Environmental Compliance

Meeting EURO IV emission standards through proven SCR (Selective Catalytic Reduction) technology, the 4DL1-21E4 demonstrates FAW’s commitment to environmental stewardship. The sophisticated aftertreatment system effectively reduces nitrogen oxide emissions whilst maintaining optimal engine performance.

Smoke emissions remain well below 0.3m⁻¹, and operational noise levels stay beneath 94dB(A), ensuring compliance with stringent urban operating requirements. This makes the engine suitable for a wide range of commercial applications, including urban delivery vehicles and long-haul transport.
